The 4WRLE10W80SJ-3X/G24EK0/A1M-303 valve is produced by Bosch Rexroth within the 4WRL Solenoid Valves series and regulates direction and volume of hydraulic flow in automated machinery. It follows the ISO 4401-05-05-0-05 porting pattern so it fits standard NG10 subplates, and its nominal size of NG10 defines the mounting and flow channel dimensions. A maximum flow of 300 l/min allows it to support medium-to-high throughput systems, while a maximum operating pressure of 250 bar lets it work in high-pressure loops without separate reducers. The pilot stage needs a minimum pilot pressure of 10 bar and draws 2.4 l/min of pilot oil to keep the spool stable across the full stroke. An actuating time of 40 ms from 0 to 100 percent command facilitates rapid load changes, and response sensitivity below 0.05 percent enables small input variations to translate into precise flow adjustments.
The electronic section accepts a ±10 V command signal for direct connection to analog controllers, and it is powered from a 24 VDC supply that simplifies wiring in industrial panels. Power draw peaks at 40 VA, so a 2.5 A time-lag fuse provides external protection against short surges. Continuous service is supported by a relative duty cycle of 100 percent, and hysteresis held below 0.1 percent minimizes deviation between increasing and decreasing commands. Internal leakage of the main valve is limited to 0.12 l/min, which reduces heat generation and maintains circuit efficiency. The housing meets IP65, allowing dependable operation in dusty or wet environments without additional enclosures.
